Pending Issues In The Modeling Of Concentrator Solar Cells

This article, published in the Proceedings of the 19th uropean Photovoltaic Solar Energy Conference, Paris, 2004, presents the ability of ATLAS-Luminous3D to simulate heterostructure Solar Cell. The modelling of concentrator solar cells for real conditions of operation inside optical concentrators is a subject almost untreated. Consequently, this work highlights the main specific situations that should be included in a realistic modelling. The results of a 2-D modelling applied to the case of a 1000 sun GaAs concentrator solar cell inside a TIR-R concentrator are presented. The necessity of going towards a 3-D modelling is also stated. This task is being carried out now at IES-UPM.
